10 Transform methods</h2>
<p>
         This package provides a few transformers for signal analysis. All transformers
         provide both direct and inverse transforms.
         <ul><li><code>FastFourierTransformer</code> (produces <code>Complex</code> results)</li>
<li><code>FastCosineTransformer</code> (produces real results)</li>
<li><code>FastSineTransformer</code> (produces real results)</li>
<li><code>FastHadamardTransformer</code> (produces real results)</li>
</ul>
